A series of 15 chalcones-bearing substituents at positions 2, 4, and 5 of rings A and B were synthesized using microwave-assisted Claissen-Smichdt condensation and evaluated for their activity against Giardia lamblia and Green monkey kidney cells. Five compounds exhibited activity against G. lamblia at IC50's 3m exhibited the highest antigiardial activity (IC50 = 1.03 mu M), even more than the positive control (metronidazole, IC50 = 1.4 mu M), and selectivity (SI = 38.9). A preliminary SAR study suggested that electrophylicity has not relationship with antigiardiasic activity, and the docking study reveals that synthesized chalcones bind at zone 3 of colchicine site, therefore presumably the action mechanism of the synthesized chalcones does not follow the Michael acceptor mechanism.
